All-Optical Coherent Lifting of Spin-Degeneracy in CsPbBr3 Nanocrystals (JW1A.91)

Presenter: Megha Shrivastava, IISER Bhopal

We coherently lift the spin-degeneracy in CsPbBr3 nanocrystals by breaking time-reversal symmetry all-optically without external magnetic field. Huge polarization-selective lifting ~50meV observed, corresponding to Rabi energy >100meV, is highest ever reported in semiconductors at room-temperature.
